Discontinuous games, such as auctions, may require special tie-breaking rules to guarantee equilibrium existence. The best results available ensure equilibrium existence only in mixed strategy with endogenously defined tie-breaking rules and communication of private information. We show that an...

Rubinstein and Wolinsky (1990b) consider a simple decentralized market in which agents either meet randomly or choose their partners volunatarily and bargain over the terms on which they are willing to trade. Intuition suggests that if there are no transaction costs, the outcome of this matching...

In this paper we consider an oligopoly and we are concerned with the effect on the price of Y and the pay-offs/utilities of the buyers and sellers of entry in the market of buyers and/or sellers. Hence our paper is concerned with comparative statics in oligopolistic markets

The purpose of this paper is to investigate the asymptotic behavior of oligopoly equilibrium in the framework of multilateral exchange when the economy is replicated a finite number of times and show that the sequence of associated price-allocation pair converges to the competitive equilibrium...

This paper reconsiders the valuation equilibrium concept (Jehiel and Samet, 2007) and proposes an additional regularity condition concerning the players' equilibrium strategies. The condition, which requires equilibrium strategies to induce the same local behaviour at all nodes with 'similar'...

We develop a theory of equilibrium market volatility in a general equilibrium duopoly with complete information. The resulting economic system possesses a property, which can be described as ‘natural volatility' of markets, even if players have complete information.Economy is described as a...

We are constructing an imperfect competition general equilibrium model, with non-consumable money and labor market; our toolkit is an equilibrium default model of Shubik-Wilson (1978). Our result has an ‘equilibrium volatility' simultaneously occurring at all three markets: labor, goods, and...

The concept of Berge equilibria is based on supportive behavior among the players: each player is supported by the group of all other players. In this paper, we extend this concept by maintaining the idea of supportive behavior among the players, but eliminating the underlying coordination...

We can often predict the behavior of those closest to us more accurately than that of complete strangers, yet we routinely engage in strategic situations with both: our social network impacts our strategic knowledge. Peer-confirming equilibrium describes the behavioral consequences of this...

This paper shows that under very general conditions, there exists a locally stable Nash equilibrium in games of strategic complements (GSC), as well as in the more general case of games with non-decreasing best response correspondences. While it is well known that in such cases a unique...
